* rfnoc: Add option to disable flow control on rx streamingmattprost2021-04-291-25/+45
| | | | | | | | | | | Disabling this feature will allow the USRP to send a continuous stream of Rx data to a host machine without throttling due to lack of flow control credits. This is unnecessary overhead on lossless transports such as pcie or aurora. Usage: add 'enable_fc=false' to stream_args.args Signed-off-by: mattprost <matt.prost@ni.com>
* rfnoc: Resolves streamer/link segfaults on pythonSteven Koo2020-08-111-11/+15
| | | | | | | | | This commit resolves a segfault that occurs during teardown. Since teardown isn't detereministic in python, there were cases where the graph would destruct before the streamers or links got chance to cleanup. This would result in a segfault. This change gives the lambda a shared pointer to the object the callback method is calling on, so that it won't destruct before being called.
* RFNoC: Add xport disconnect callbacksmichael-west2020-08-041-7/+20
| | | | | | | | | | | | Transports were not disconnecting their links from the I/O service upon destruction, leaving behind inaccessible send and recv links used by nothing. This led to I/O errors after creating several transports. Added callbacks to transports to automatically disconnect their links from the I/O service when the transport is destroyed. Updated all callers to supply a disconnect callback. Signed-off-by: michael-west <michael.west@ettus.com>
* transport,usrp: Make available packet-based flow controlAlex Williams2019-12-201-11/+16
| | | | | | | | DPDK provides a fixed number of fixed-size buffers for the receive window, so it needs packet-based flow control to avoid dropping packets. This change enables counting by packets. Co-authored-by: Ciro Nishiguchi <ciro.nishiguchi@ni.com>
* rfnoc: Merge I/O service device args with stream argsCiro Nishiguchi2019-11-261-2/+4
| | | | | This makes it possible for users to put I/O service-related args in either the device args or stream args.
* uhd: Introduce I/O service managerAaron Rossetto2019-11-261-18/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | - Implement I/O service detach link methods - The I/O service manager instantiates new I/O services or connects links to existing I/O services based on options provided by the user in stream_args. - Add a streamer ID parameter to methods to create transports so that the I/O service manager can group transports appropriately when using offload threads. - Change X300 and MPMD to use I/O service manager to connect links to I/O services. - There is now a single I/O service manager per rfnoc_graph (and it is also stored in the graph) - The I/O service manager now also knows the device args for the rfnoc_graph it was created with, and can make decisions based upon those (e.g, use a specific I/O service for DPDK, share cores between streamers, etc.) - The I/O Service Manager does not get any decision logic with this commit, though - The MB ifaces for mpmd and x300 now access this global I/O service manager - Add configuration of link parameters with overrides Co-Authored-By: Martin Braun <martin.braun@ettus.com> Co-Authored-By: Aaron Rossetto <aaron.rossetto@ni.com>
* rfnoc: Unify endianness of transportsAlex Williams2019-11-261-1/+1
| | | | | Ethernet now uses the same serialization of the RFNoC stream as all the other transports.
